**Core Concept**
Congestive cardiac failure (CCF) is characterized by the heart's inability to pump enough blood to meet the body's demands, leading to an increase in various physiological parameters. **Cardiac output** and **peripheral resistance** are key factors affected in CCF.

**Why the Correct Answer is Right**
Since the correct answer choice is missing, let's consider a general approach to CCF: in CCF, there's an increase in **preload**, **afterload**, and **venous pressure** due to the heart's reduced pumping efficiency. However, without the specific options, we can't directly identify why one choice is correct over the others.

**Why Each Wrong Option is Incorrect**
**Option A:** Would be incorrect if it stated something like "increase in cardiac output" because CCF is characterized by a decrease in cardiac output.
**Option B:** Might be incorrect if it mentioned an increase in a parameter that actually increases in CCF, such as **aldosterone** levels.
**Option C:** Could be incorrect if it referred to an increase in a factor that indeed rises in CCF, like **vascular resistance**.
**Option D:** Would be the correct choice if it mentioned a parameter that does not increase in CCF, but without the options, we can't specify.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that CCF leads to increased **atrial natriuretic peptide (ANP)** and **brain natriuretic peptide (BNP)** levels due to atrial and ventricular stretch, which is a diagnostic clue.

**Correct Answer:** D. Decrease in cardiac output
